Question 1

What is the time complexity of the divide and conquer algorithm for the closest pair of points?

  • O(n)
  • O(n log n)
  • O(n²)

💡 Hint: Consider both sorting and the number of comparisons.

Question 2

True or False: A brute-force solution is sufficient for any number of points.

  • True
  • False

💡 Hint: Think about how performance varies with larger datasets.

Challenge Problems

Push your limits with challenges.

Question 1

Design an efficient algorithm for identifying the closest pair of points in a three-dimensional space and compare it with the two-dimensional solution.

💡 Hint: Consider how the layers of data might interact and what modifications you need to track.

Question 2

Given a large dataset of points, create a visual representation of the divide and conquer process showing how points are divided and sorted.

💡 Hint: Think about how you can simplify the visual representation while illustrating the main computational steps.
